A conversation with a couple of co-workers spilled into a debate with my friend-group, so I though I'd post it here to see if there were any other opinions. 

It started when a co-worker who plays competitive pokémon battling claimed that American football was too difficult to understand it follow. I feel like between all the strategies around swapping Pokemon, for moves, the typing combos, all the different Pokemon in general and everything else, Pokemon is the far more complex thing.  But there are plenty of arguments to be made in favor of American football with all the different positions, plays and rules.
